Jennifer Aniston and Justin Theroux Are Twins Now

Jennifer Aniston and Justin Theroux are slowly becoming "that" couple. You know, the couple that ignores their friends at dinner parties because they're too busy groping each other under the table. And Jennifoux has taken it up a notch by dressing alike. Gag.

The two were spotted walking in New York City's West Village the other day. They both wore black leather jackets, black shirts, aviators, and military boots. They were pretty much identical except that Justin wasn't carrying an oversized purse.

But these two are by no means the first celebrity couple to dress alike. And away we go:

Jennifer Garner and Ben Affleck: When he was with Jennifer Lopez, Ben really cleaned up his act. You think J.Lo is going to be seen on the red carpet with a guy wearing a Red Sox hat and old jeans? But when Ben started dating Jennifer Garner, his look got much more relaxed.

Katy Perry and Russell Brand: Thankfully, she changed her hair color. Because before, I couldn't tell the difference between Katy and Russell, at least from the neck up. They had the same jet black, wavy hair and always seemed to coordinate their outfits. He's wearing a gray scarf? She's wearing a gray shawl. She's wearing a long white gown? He's wearing a white suit. She's wearing a cupcake bra, he—okay, not every outfit is coordinated.

Brad Pitt and everyone: You already knew about this one. Brad Pitt is a relationship chameleon. He pretty much copies the style of whoever he's dating at the time. When he was with Gwyneth Paltrow, Brad adopted a sleek, WASP-friendly look. At one point, it looked like he and Gwyneth even had the same hairstyle. Then, when Brad moved on to Jennifer Aniston, he colored his hair a shade darker to match hers. He also donned the more casual, California style that Jen is known for. But when Brad ditched Aniston for Angelina, he went even darker. And got lip injections. Okay, not the lip injections part.

Marilyn Manson and Dita Von Teese: Okay, so they both looked really similar even before they got together. But once they started appearing on the red carpet together, you could really see it. They looked like sister and really, really creepy brother.

Tom Cruise and Katie Holmes: Especially when Holmes got her bob cut, she and Tom looked nearly identical. I'm guessing Tom Cruise is so egotistical, he wants to pretend he's married to himself.
